I enjoyed the lecture while thinking, "What would I do in this situation?" It is a lecture that can guide you if you have never worked on a large-scale system before. If you have experience, it is a lecture where you can experience different perspectives and realize, "It can be done this way too." I think it would feel even more realistic if we could experience the service actually running by generating virtual traffic.

The lecture was easy to understand because it used a simple message board as an example, and it was a great opportunity to take a step further in understanding architecture.

It was great to be able to consider various strategies using Redis and Kafka in an MSA architecture.

There's a lot to learn from the lectures. Each chapter has keywords to study, and it's great that you focus on those and include code writing as well. The current popular post - the 36-minute lecture on Consumer implementation was a bit difficult to get through, so it would be good if you could upload the lectures divided into smaller segments. Just improving this part would make it much better. Students can divide it up themselves when listening, but it would be more appropriate to have it organized as separate lectures.

I was able to learn the essential core concepts about caching in a concise and efficient way. As you applied each caching method step by step, you introduced the problems with each approach along with alternative caching methods that could solve them, which greatly helped me understand things progressively. The lecture was so engaging that I ended up purchasing your bulletin board course as well haha Looking forward to many more great lectures from you!

I don't think there's a better course than this for those working in backend development with Java in real-world settings. The difficulty level is truly intermediate or above. However, if you fully master the concepts and skills presented here and make them your own, I'm confident you'll become a backend developer who has advanced one or two levels further. Thank you so much for the excellent lecture, instructor.

You can learn MSA basics in an easy and fun way.

Thank you for the excellent lecture.

Overall, it was great for learning

Through Kuke's lectures, I was able to learn and think about many aspects of large-scale systems, which made it a truly grateful learning experience. One thing I was curious about while completing the course was that throughout the entire lecture, from start to finish, Kuke coded directly while explaining, which was very helpful. I'm wondering if you refer to any materials while coding during the lectures... Watching you implement clean and efficient code so smoothly makes me worry a lot about whether I'll ever be able to code like that, translating my logic into code so quickly and naturally...
